将录制的音频从iOS应用保存到mySQL数据库

Question

I am working on a project that uploads data to a mySQL database from an iOS app through PHP and AFNetworking. I have code that successfully records and saves an audio file to a folder on my server and saves the relative path in the database. As a test, I download them from the folder they were saved to and I can play them on my computer, however when I try to play a sound in a working app it does not play back at all. I have also tried saving the files as different audio formats but I don't know what the problem is. I'm not sure if it's to do with my code or not. The following is my PHP code:

if ((($_FILES["audio"]["type"] == "audio/mp3")
|| ($_FILES["audio"]["type"] == "audio/mp4")
|| ($_FILES["audio"]["type"] == "audio/m4a")
|| ($_FILES["audio"]["type"] == "audio/wav")
|| ($_FILES["audio"]["type"] == "audio/caf")
|| ($_FILES["audio"]["type"] == "audio/mpeg3")
|| ($_FILES["audio"]["type"] == "audio/mpeg"))

&& ($_FILES["audio"]["size"] < 1000000))
  {
  if ($_FILES["audio"]["error"] > 0)
    {
    echo "Return Code: " . $_FILES["audio"]["error"] . "<br />";
    }
  else
    {
    echo "Upload: " . $_FILES["audio"]["name"] . "<br />";
    echo "Type: " . $_FILES["audio"]["type"] . "<br />";
    echo "Size: " . ($_FILES["audio"]["size"] / 1024) . " Kb<br />";
    echo "Temp file: " . $_FILES["audio"]["tmp_name"] . "<br />";

    if (file_exists("audio/" . $_FILES["audio"]["name"]))
      {
      echo $_FILES["audio"]["name"] . " already exists. ";
      }
    else
      {
    $audio_name =  $_FILES["audio"]["name"];
      $audio_path =  "audio/$audio_name";

      move_uploaded_file($_FILES["audio"]["tmp_name"], $audio_path);

      $sql = "INSERT INTO audiotable (audiopath)  
  VALUES ('$audio_path')";
          $result = mysql_query($sql);
          if($result)
      {
            echo 'Upload successfully';
      }
      else
      {
            echo 'ERROR: Upload Failed';
      }
      }
    }
  }
else
  {
  echo "Invalid file";
  }

This is the AVPlayer and its settings:

    NSArray *pathComponents = [NSArray arrayWithObjects:                              
    [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject],@"MyAudioMemo.caf", nil];
    NSURL *outputFileURL = [NSURL fileURLWithPathComponents:pathComponents];

    AVAudioSession *session = [AVAudioSession sharedInstance];
    [session setCategory:AVAudioSessionCategoryPlayAndRecord error:nil];

    NSMutableDictionary *recordSetting = [[NSMutableDictionary alloc] init];

    [recordSetting setValue:[NSNumber numberWithInt:kAudioFormatAppleIMA4] forKey:AVFormatIDKey];
    [recordSetting setValue:[NSNumber numberWithFloat:44100.0] forKey:AVSampleRateKey];
    [recordSetting setValue:[NSNumber numberWithInt: 2] forKey:AVNumberOfChannelsKey];
    [recordSetting setValue:[NSNumber numberWithInt:AVAudioQualityMin] forKey:AVEncoderAudioQualityKey];

    recorder = [[AVAudioRecorder alloc] initWithURL:outputFileURL settings:recordSetting error:NULL];
    recorder.delegate = self;
    recorder.meteringEnabled = YES;
    [recorder prepareToRecord];

And this is the upload code:

NSData *data = [NSData dataWithContentsOfURL:recorder.url];
int randomAudio = arc4random() % 9999999;
NSString *audioName=[NSString stringWithFormat:@"%d-audio.caf",randomAudio];
[manager POST:@"http://mywebsite.com/upload.php" parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
[formData appendPartWithFileData:audioData name:@"audio" fileName:audioName mimeType:@"audio/caf"];
    } success:^(AFHTTPRequestOperation *operation, id responseObject) {       
        NSLog(@"Success: %@", responseObject);
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        NSLog(@"Error: %@", error);
    }];
    }

Please let me know if you have any suggestions or if you know what the problem is, as I have no clue. Thanks in advance!

Turns out my code wasn't the problem, it works perfectly fine! So feel free to use it. Turns out my problem was different. See this post: Unable to play MP4 video file from mainBundle
